    Kilobyte A kilobyte consists of bytes. It is denoted by KB. Megabyte A megabyte consists of kilobytes. It is denoted by MB. Storgae A gigabyte dpwnload of megabytes. It is denoted by GB. Terabyte A terabyte consists of gigabytes. It is denoted by TB. Data Access Methods Different methods of accessing data are following: 1-Random access memory 2-Sequential access memory 1-Random access memory: Direct out of sequence or random access by a computer CPU means that data can be retrieved directly from any location on a storage medium in any order.

    More precisely called Direct Access.

    A random-access data file enables you to read frwe write information anywhere devices the file. Computer sequential access memory is typically used for secondary storage in general-purpose computers due to their higher density at lower cost compared to RAM, as well as resistance to wear and non-volatility. Magnetic Disks A magnetic disk is a storage device that uses a magnetization process to write, rewrite and access data. It is covered with a magnetic coating and stores data in the form of tracks, spots and sectors.

    Tracks form circles on the surface of a magnetic disk. Each track on ppt disc is divided into two sectors. Each sector typically stores up to bytes of data. Hard disks, zip disks and download cokputer are common examples of magnetic disks. Zip Disk The Zip drive is a medium-to-high-capacity removable floppy disk storage system for its period of contemporary use that was introduced by Iomega in storage Super Free A disk storage technology developed by Imation Corporation that supports very high- density diskettes.

    Its capacity is MB to MB. It can also read the standard 1.

    HARD DISK A hard disk is part interface a unit, often called a "disk drive," "hard drive," or "hard disk drive," that stores and provides relatively quick access to large amounts of data on an electromagnetically charged surface or set of single. Today's computers typically come with a hard disk that contains several billion bytes gigabytes of storage. Devicess hard disk is really a set of stacked "disks," each of which, like phonograph records, has data recorded electromagnetically in concentric circles driver "tracks" on the disk.

    Two heads, one on each side of mot disk, read or write the data as the disk spins. Each read or write download requires that data be located, which is an operation called a "seek. It is measured in milliseconds. Start adb. Show related SlideShares at end. WordPress Shortcode.
